Answer:

Ah! Geometric sequences, Eh? Sucks I know....

Step-by-step explanation:

So first, we need to find the factor of this(been a while since I have done this)

r=\frac{24}{48} =\frac{1}{2}

So we found the relationship! Now we find the entire equation.

So we know the first term, 96, so let's use it!

a_{n} =96*(\frac{1}{2})^{n-1}

So there is the equation!

Now to find the 10th term.

a_{n} =96*(\frac{1}{2})^{n-1}\\a_{10} =96*(\frac{1}{2})^{9}\\a_{10} =96*\frac{1}{2^{9} } \\a_{10}=0.1875

There you have it!

Hope this Helps!

P.S. Stay Safe!

PLZ HELP GUYS. Solve the equation:5 2x+1-3(5x+1)+10=0​
rodikova [14]

Answer:

(52x + 1) -  3 • (5x + 1)) +  10  = 0

37x + 8  = 0

3.1      Solve  :    37x+8 = 0

Subtract  8  from both sides of the equation :

                     37x = -8

Divide both sides of the equation by 37:

                    x = -8/37 = -0.216

x = -8/37 = -0.216

Find the perimeter of the following shape, rounded to the nearest tenth:
OLga [1]

Answer: the perimeter of the shape is 19.1

Step-by-step explanation:

To determine the length of each side of the quadrilateral, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side

For line AD,

AD² = 2² + 4² = 4 + 16 = 20

AD = √20 = 4.47

For line AB,

AB² = 1² + 5² = 1 + 25 = 26

AB = √26 = 5.1

For line BC,

BC² = 2² + 4² = 4 + 16 = 20

BC = √20 = 4.47

For line CD,

CD² = 1² + 5² = 1 + 25 = 26

CD = √26 = 5.1

The perimeter of a plane figure is the distance around the figure. Therefore

Perimeter = AB + AB + BC + CD

Perimeter = 4.47 + 5.1 + 4.47 + 5.1 =

19.1
